Does the KC868-A6 V1.4 board provide a 5V output for DS18B20 sensors? - GetBK - 04-29-2025
Hi everyone,
I'm using the Kincony KC868-A6 V1.4 board and planning to connect several DS18B20 temperature sensors. I know these sensors can work with 3.3V, but they tend to be more stable with a 5V power supply—especially when using longer cables.
Does this board provide a dedicated 5V output pin that I can use to power the DS18B20 sensors? If so, where exactly can I find it on the board?
Any help or insights would be greatly appreciated!
Thanks in advance!

we don't recommended get 5v power from PCB, because if the load is heavy, will let the board not stable. i don't know how many ds18b20 sensors you want to use. how long cable you want to use. if you have many sensor need connected, you can use a extend 5v power supply and good quality cable is better.
